In many areas, the smoke is thick and the sky is orange.
Here's what we know about some of the victims and those still missing:
The victims lost
Charles and Sara Rippey
The Rippeys' love affair started early -- Charles was in the sixth grade, and Sara was in the fourth grade, their son Mike said.
After Charles went to fight in World War II, he returned and had five children with his beloved, Mike Rippey told KPIX. They recently celebrated their 75th wedding anniversary.
Mike Rippey said he believes his father died trying to save his mother. Charles Rippey's body was found in the charred remains of the hallway just outside where his wife was sleeping.
"From where they found his body, he was trying to get from his room to her room," he said. "He never made it. Even if he had gotten there, he wouldn't have been able to get her out. ... And there is no way he would have left."
Christina Hanson saw the flames coming from afar. But the 28-year-old, who lived in an apartment next to her father's house in Santa Rosa, used a wheelchair.
Hanson first tried to reach her father, but to no avail, her aunt Cathy Riordan said. She then called her father's ex-wife, saying she saw an inferno and was scared.
Concerned neighbors told the family they called 911 to the property, but it's unclear what happened after those calls, Riordan said.
After a day of panic and uncertainty, Christina's cousin confirmed she had died.
"Sadly, we just found out that Christina did not survive the fire," cousin Brittney Vinculado said Wednesday.
Hanson's father, 55-year-old Michael Hanson, suffered third-degree burns on over half his body and was at Sutter Santa Rosa Regional Hospital before it was evacuated, Riordan said. He was in a medically induced coma.
Sutter tried to transfer him by helicopter to San Francisco for treatment, but smoke prevented the chopper from taking off, Riordan said. Instead, he was transferred by ambulance.
Riordan said she believes her brother was injured trying to help his daughter.
"I know that's how he got burned," she said. "(He) was trying to save her."
The loved ones still missing
The situation could worsen, as firefighters keep battling 22 wildfires that have already scorched 170,000 acres.
Rachael Ingram last heard from her close friend, Mike Grabow, late Sunday night when he told her the air was smoky as he drove to his Santa Rosa home.
"He knew it was bad," the 28-year-old Ingram told CNN.
She and Grabow, 40, had been at the Cooperage Brewing Company in Santa Rosa, where she is a bartender. The pair, friends for more than eight years, had been looking at maps of where the wildfires were before Grabow left to drive home.
Ingram, also a Santa Rosa resident, said she reported Grabow missing right away.
Ingram wrote on Facebook that she checked hospitals and the Red Cross shelter database, and listed Grabow with the fire department and sheriff's hotline.
"We have a pretty solid core group of friends that have been looking for him," she said. "If he didn't show up at any of our houses,that's an immediate red flag for us. I called his brother first and alerted him and asked him to help," she said.
The brother went to Grabow's home on Monday and discovered the blaze had destroyed the home. The fire had melted the glass on Grabow's truck, Ingram said.
"He has tons of family in Idaho that are really worried about him, as well as family in Washington. I want to acknowledge what they're going through," Ingram said.
"They're absolutely terrified and we're trying to help them," she added.
